Infectious diseases and the dental office.

Dentists and other health care workers have long been concerned about a variety of infectious agents that may be transmitted within the dental setting. In recent years there has also been widespread concern among the general public. Many infectious diseases, including HIV, hepatitis, tuberculosis and syphilis, are important both because of their potential transmissibility and because the first manifestations of the disease may appear in the oral cavity. A knowledge of these diseases will allow the practitioner to recognize associated lesions and also to take appropriate steps to minimize the risk of transmission in the dental office.

Diagnostic dilemma involving calcification in the parapharyngeal space: metastatic thyroid carcinoma masquerading as a deep lobe parotid mass.

As the parapharyngeal space is difficult to examine clinically, the radiographic distinction between deep lobe parotid masses and extraparotid tumors is essential in determining the surgical approach. We describe the case of a 53-year-old woman who presented with facial pain consequent to metastatic papillary thyroid carcinoma of the parapharyngeal space. A highly unusual pattern of calcification was present in the mass as observed by panoramic radiography and computed tomography. Parapharyngeal metastasis as the presenting feature of occult thyroid carcinoma has only been described four times previously in the medical literature.

Dental aspects of cardiac transplantation.

This article does not cover all possible dental situations, but it is hoped that it will provide a framework on which a medical or dental consultant can develop his or her own comprehensive oral evaluation protocol for use in the screening of prospective cardiac transplant patients. It is always important for the dental consultant to remember a prospective recipient patient's primary health concern--that is, end-stage cardiac disease. The consultant should remember that many of the usual considerations for dental treatment planning must be modified and the significance of dental health placed into its proper perspective in the overall care of the cardiac transplant patient.

Ectopic gingival sebaceous glands presenting as localized periodontitis.

The development of ectopic gingival sebaceous glands is a very unusual condition which is histologically similar to Fordyce's granules when they occur within the buccal or labial mucosa. In this report, we present a rare case of ordinarily innocuous, ectopic gingival sebaceous glands, which presented clinically and radiographically as localized advanced periodontitis. Histological and immunocytochemical evaluation of tissue removed from the periodontal lesion following excisional biopsy supported the diagnosis of an ectopic gingival sebaceous defect. This case illustrates the necessity of considering less frequently occurring entities in the differential diagnosis of localized lesions which appear to be periodontal in origin.

Gingival manifestations of Wegener's granulomatosis.

Localized Wegener's granulomatosis is characterized by necrotizing granulomatous disease affecting the upper and lower respiratory tracts, mucosa, and skin. Without treatment, disseminated necrotizing vasculitis and focal necrotizing glomerulonephritis usually follow. Although oral lesions are relatively common, they have been infrequently described and have rarely been reported as the sole manifestation of this disease. In this report, we present two cases of early Wegener's granulomatosis which featured hyperplastic gingival lesions as the initial presenting lesion. Clinical findings and histological evaluation of tissue obtained from the gingival lesion following incisional and excisional biopsies supported the diagnosis of Wegener's granulomatosis. These cases illustrate that less-frequently occurring entities should be considered in the differential diagnosis of localized gingival lesions which fail to respond to conventional therapy.

Medical conditions of importance in dental practice.

Good dental practice requires that a dental practitioner be aware of those medical conditions that might present first with oral manifestations and those for which special considerations are required before dental treatment is rendered. In view of the rapid changes in the understanding and treatment of disease, it is essential that a dentist be current in his knowledge of medicine and be aware of the established and accepted methods of patient management.

Controversies in oral medicine.

This article reviews two conditions commonly seen in oral medical practice. Aphthous ulceration and lichen planus are two very perplexing problems with controversies about etiology, pathogenesis, diagnosis, management, and, in the case of lichen planus, malignant potential.
